ABSTRACT

Maximum protein production in the conversion of brewery spent grains into fungal single-cell protein (SCP) via submerged fermentation using Chaetomium globosum was obtained after thirty-six (36) hours of fermentation. Pretreatment of substrate with alkali gave better results than pretreatment with steam which produced results comparable with that of the control (no pretreatment). Addition of a combination of urea and molasses enhanced protein production more than addition of either molasses or urea alone.

Maximum crude protein contents of 38.48%, 30.12%, and 29.011 using a combination of urea and molasses was obtained from the alkali pretreated, steam pretreated, and untreated substrates, respectively. Protein content was upgraded by 96.93%, 54.14%, and 48.46% for the three pretreatments. Crude fiber contents of the final SCP products were higher than the original owing to the chitins from the cell walls of the fungi.
